To determine if a blue and white British Shorthair is purebred, you should first examine the cat's face. A purebred blue and white British Shorthair will have a distinct 'V' shaped marking on its face, where the blue and white colors are evenly distributed. If the facial markings deviate significantly from this pattern, it may indicate a mixed breed.

Next, observe the cat's head. Purebred blue and white British Shorthairs possess a large, rounded head. Their ears are triangular, small, and pointed, and they have large, round eyes. The fewer of these characteristics a cat possesses, the more likely it is to be a mixed breed. Conversely, a cat exhibiting all these traits is more likely to be purebred.
Finally, assess the cat's body type. Purebred blue and white British Shorthairs have short, stocky, and robust legs, a slightly curved and long tail, and a short, thick neck. A lack of these physical attributes suggests a less purebred lineage. The more of these characteristics a cat exhibits the more likely it is to be purebred.
Blue and White British Shorthair Price Range
The price of a blue and white British Shorthair typically ranges from $2,500 to $10,000. The higher the quality of the cat's physical attributes, especially the clarity and symmetry of the 'V' shaped facial markings, the higher the price. A purebred blue and white British Shorthair should have a blue back and a white underside. The blue and white markings on the face should form distinct triangles, with blue forming the up-pointing triangle and white the down-pointing one. This distinct color combination enhances the overall cuteness of the British Shorthair.
